Abstract

La présente invention concerne un système de réseau. Le système de réseau selon un mode de réalisation de la présente invention comprend: un premier élément qui peut exécuter une fonction prédéfinie et qui a un premier code unique; et un second élément qui peut échanger de l'information avec le premier élément sur une liaison de communication pour le premier élément et qui a un second code unique. Lorsqu'une commande de mise en relation est entrée dans le premier élément ou le second élément, un signal de connexion est produit par l'élément au moyen de la commande entrée, puis une adresse de communication ainsi que les codes uniques de chacun des éléments sont échangés entre l'élément qui a produit le signal de connexion et l'élément qui reçoit le signal de connexion, le système de réseau est converti dans l'état d'attente de liaison de communication lorsque l'échange d'information entre le premier élément et le second élément ne se produit pas pendant la période de temps prédéfinie.
